Phosphatase Classification: Fold CC1: Superfamily CC1: OCA
The OCA family is named after the five member genes in yeast (OCA1-5 = Oxidant-induced Cell-cycle Arrest). The family is also called plant and fungi atypical (PFA)-DSPs [1, 2].
Contents
Evolution
OCA is found in most eukaryotes other than eumetazoa. We have seen it in fungi, plants, protists, monosiga, and sponge.
Domain
OCA has a single domain, a phosphatase domain of fold CC1.
Functions
Yeast OCA members are involved in cell cycle arrest in response to oxidative damage[3], in telomere capping [4], in actin organization [5]. OCA3 has been shown to control intracellular localization of Gln3 (a phosphorylated transcriptional activator), in cooperation with Npr1 kinase [6].
